Scope of Application

110kV Computing Power Transformer

This series of 110kV oil-immersed computing power transformers is specially developed and designed for high-power, high-reliability, and high-stability power supply scenarios, focusing on large-scale digital infrastructure such as AI computing centers, supercomputing clusters, and high-density data centers. It is a core power transformation equipment that connects the public 110kV power grid to the medium-voltage power distribution system of the computing center, ensuring the safe, continuous and efficient operation of large-scale computing equipment. Its detailed application scope is as follows:

1. Large-Scale AI Intelligent Computing Centers

It is the core main transformer for large-scale AI intelligent computing centers (including national-level intelligent computing hubs, regional intelligent computing centers, and enterprise-level AI computing bases). These centers are equipped with tens of thousands or even hundreds of thousands of high-performance GPU/TPU chips, forming large-scale computing clusters with single-machine cabinet power up to 50-400kW and total power consumption reaching hundreds of megawatts. The 110kV computing power transformer is responsible for stepping down the 110kV high-voltage power from the grid to 35kV or 10.5kV medium-voltage power, which is then distributed to each power distribution cabinet and computing node through the medium-voltage distribution system. It is specially optimized for the characteristics of sharp and frequent load fluctuations of AI chips (load changes of 30%-100% in milliseconds), with strong overload capacity and impact resistance, ensuring that the voltage stability meets the strict requirements of AI chip operation (voltage fluctuation ≤ ±3%), and avoiding equipment downtime or damage caused by voltage instability.

2. Supercomputing Centers and High-Performance Computing (HPC) Systems

It is widely used in national supercomputing centers, university supercomputing platforms, and industrial supercomputing projects. Supercomputers and HPC systems are mainly used for large-scale scientific computing, numerical simulation, meteorological forecasting, aerospace simulation, and other high-intensity computing tasks, requiring a continuous, stable, and low-loss power supply. The 110kV computing power transformer provides large-capacity power support (31.5MVA-240MVA) for the entire supercomputing system, with low no-load loss and load loss (meeting GB1094 first-class energy efficiency standards), which can effectively reduce the overall energy consumption of the supercomputing center and improve the operation efficiency of the system. At the same time, its high short-circuit withstand strength and reliable insulation performance can effectively resist the impact of power grid fluctuations and ensure the uninterrupted operation of supercomputing tasks that often last for several days or even weeks.

3. High-Density Data Centers and IDC Parks

For large-scale IDC parks, cloud computing data centers, and enterprise-level high-density data centers, the 110kV computing power transformer serves as the main power supply equipment for the entire park or data center. With the rapid development of cloud computing, big data, and 5G applications, the density of server cabinets in data centers is increasing, and the total power demand is constantly rising (single data center power consumption up to 100MW+). The 110kV computing power transformer can adapt to the high-power, high-density power supply needs of data centers, and cooperate with the 35kV/10kV medium-voltage distribution system to realize multi-zone, redundant power supply, ensuring the 7×24h continuous operation of the data center (the core requirement of IDC operation). In addition, its low-noise design (noise ≤ 65dB) is suitable for data centers built in urban areas or industrial parks, reducing environmental pollution.

4. Digital Economy and New Infrastructure Supporting Power Systems

It is an important supporting equipment for the construction of digital economy and new infrastructure. In the fields of smart cities, industrial Internet, Internet of Things, and big data industrial parks, a large number of high-power computing equipment, data storage equipment, and communication equipment need stable and efficient power supply. The 110kV computing power transformer can connect the public power grid to the power supply system of these digital infrastructure projects, providing large-capacity, low-loss, and intelligent power transformation services. It can be integrated with intelligent monitoring systems (such as oil temperature monitoring, winding temperature monitoring, partial discharge monitoring, and dissolved gas analysis), realizing real-time monitoring of transformer operation status, early warning of potential faults, and improving the reliability and intelligent level of the power supply system.

5. Special High-Power Computing Scenarios

It is also applicable to various special high-power computing scenarios that require high-reliability and high-stability power supply, including:

– Military computing centers and defense science and technology computing platforms, which require extremely high reliability and anti-interference performance of the power supply system to ensure the smooth progress of confidential computing tasks;
– Medical big data computing centers and biological information computing platforms, which need continuous and stable power supply to ensure the accuracy and continuity of medical data analysis and biological simulation;
– Financial data centers and quantitative computing platforms, where the stability of the power supply system is directly related to the safety of financial transactions and the accuracy of quantitative analysis, and the 110kV computing power transformer can provide reliable power guarantee.

In summary, the 110kV computing power transformer is mainly used in large-scale computing scenarios with high power demand, strict stability requirements, and frequent load fluctuations. It is the core power transformation equipment for the digital economy, artificial intelligence, and new infrastructure construction, providing a solid power foundation for the stable operation of various high-performance computing systems.
